How do people use 上の空?

Everyday Japanese for when your body is present but your mind has floated off. It often comes with で plus a verb (“上の空で話を聞く”, to listen with your mind elsewhere) or as a description with だ (“今日は上の空だね”). Teachers, partners and bosses all say it, usually as a complaint.

Where does 上の空 come from?

The Daijisen (via Kotobank) lists three senses: being distracted, the sky above, and something unreliable or without basis. It quotes The Tale of Genji (the Yūgao chapter) for the sky sense, where a moon drifts in the upper sky. The dictionaries don’t explain how the sky came to mean a wandering mind, but the picture of thoughts floating off upward is easy to see.

Mistakes learners make with 上の空

Reading 上 as うえ. In this phrase it’s the old reading うわ, as in 上着 (uwagi), so “うえのそら” sounds wrong.
